Question

I have a static variable on appDelegate declared like this:

appdelegate.h file:

+(NSMutableArray*)allBanco;
+(void)setAllBanco:(NSMutableArray*)value;

appdelegate.m file:

static NSMutableArray * allBanco;

+(NSMutableArray*)allBanco
{
    return allBanco;
}

+(void)setAllBanco:(NSMutableArray*)value
{
    if(allBanco != value)
    {
        [allBanco release];
        allBanco = [value copy];
    }
}

I tried to acess it on other class
on .m file:

#import "AppDelegate.h"

    [[AppDelegate allBanco] addObject:testeObj];

i cant understand why,i can log the

NSLog(@"%i",[[AppDelegate allBanco] count]);

and goes ok.

I tried :

    NSMutableArray * temp = [[[NSMutableArray alloc]init]autorelease];
    temp = [AppDelegate allBanco];
    [temp addObject:testeObj];
    [AppDelegate setAllBanco:temp];

and doest work.

Answer 1

Considering you created your array properly, keep in mind that -copy returns an immutable copy, so you may crash later when modifying it.

Now that you added your error, I’m quite sure this is indeed the problem:

-[__NSArrayI addObject:]: unrecognized selector sent to instance

You tried to add an object in a NSArray, not a NSMutableArray. Try using -mutableCopy.
